Switch IAVL Store query to use ics proofs (#6324)
* switch iavl store to use ics proof

* fix proofs to return for correct height

* appease linter

* Register commitment op correctly

* Make CommitmentOp generic over all ics23 specs (#6331)

* Make the CommitmentOp generic over all ics23 ProofSpecs, using Type to distinguish

* Register SimpleMerkle ics23 proof op as well

* Addressed linter issues

* move commitment proof to types

* Apply suggestions from code review
